China's State Council announced the appointment of nine officials yesterday, with Yin among them.

Yin, 56, from Shengzhou, Zhejiang, obtained his doctorate in economics from Nankai University in Tianjin.

He began his career in trade in 1984, and worked for the predecessor to China's Ministry of Commerce for two decades.

Between 1984 and 2006, Yin had worked with the Ministry of Foreign Trade and Economic Cooperation, the Ministry of Commerce, China's Permanent Mission to the United Nations Industrial Development Organization and China International Center for Economic and Technical Exchanges.

Between 2006 and 2011, Yin was Minister Counselor of the Economy and Commerce at the Brussels-based China's Mission to the European Union.

From 2011 to 2013, he was appointed director-general of the Department of International Trade and Economic Affairs of China's Ministry of Commerce.

Between 2013 to 2014, Yin also took charge of World Trade Organization-related affairs at the same ministry.

From 2014 and 2019, he was appointed vice-chairman of China Council for the Promotion of International Trade.

And in 2019, he was appointed as deputy director of the Hong Kong, Macau, Taiwan and overseas Chinese committee of the Chinese People's Political Consultative Conference.

Separately, the head of the Chinese Mission to the United Nations Office at Geneva, Chen Xu, said China was firmly opposed to countries disseminating misinformation by "abusing" the platform of the Human Rights Council.

Chen hit back at countries including the US, UK, Canada, Australia and those within the EU, saying they had spread false information about China's human rights situation.

"China has made remarkable achievements in the field of human rights by putting people at the center," he said.

On Hong Kong, Chen backed the national security law, as it had restored peace from the city's chaos.

He also said the changes in the electoral system could consolidate the principles of "patriots governing Hong Kong" and "one country, two systems."
